1'0 all, whom it may concern.-

Be it known that I, JONATHAN HALEY, a citizen of the United States of America, residing at Akron, in the county of Summit and State of Ohio, have invented certain new and useful Improvements in (Vere-Feeding Apparatus for Leers or Annealing-Furnaces; and I hereby declare the following to be a full, clear and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.

This invention relates to improvements in apparatus for conveying glassware-and other ware to be annealed into and through an an nealing oven or chamber.

This invention pertains more especially to apparatus comprising an annealing-chamber open at its rear and ware-discharging end and heated by a heating-burner or heating appliance at its opposite and forward end and having a lateral doorway orinlet in one side wall thereof and near the said heating means for accommodating the passage of ware to be annealed into the said chamber and onto an endless conveyer arranged to bear the said ware longitudinally of and through thesaid chamber in t'he direction of the rear end of the chamber.

This invention chiefly comprises meritorious means for feeding the ware through the said inlet onto the aforesaid conveyer and for arranging the said ware in rows upon and transversely of the said conveyer, improved means for intermittently operating the said conveyer, and such a relative arrangement and operation of the'parts of the apparatus that the members of each row of ware to be fed to and upon the said conveyor shall be successivel y delivered to the said conveyer in good condition and without injury to ware already delivered to the said conveyer and that the said conveyer shall upon the formation of each row of ware fed to the said conveyer be automatically actuated long enough to carry the said row of ware toward the rear and discharging end of the annealing-chamber and out of the way f the path of ware next fed onto the said conveyer in forming thenext succeeding row of ware on the conveyor.

The object of this invention is to provide apparatus whereby the ware which is to be annealed is conveyed into and through the said chamber with facility and without liability of breakage of or injury to the ware.

With this object in view and to the end of realizing other advantages hereinafter appearing this invention consists in certain features of construction and combinations of parts, hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a top plan, partly in section, of a portion of an annealing oven or chamber and the greater portion of the apparatus embodying the said invention, and portions are broken away in this figure to reduce the size of the drawing. Fig. 2 is a side elevation of the same, and portions are broken away and in section in this figure to reduce the size of the drawing and to more clearly show the construction. Fig. 3 is a top plan, in horizontal section, taken through the annealing-chambet, and portions are broken away in this rigure to reduce the size of the drawing.

Figs. from 5 to 18, inclusive, are drawn on a larger scale than the first four figu res.

Referring to the drawings, A designates the casing of an annealing dven or chamber 1, which, as shown in Figs. 1, 3, and 4;, is open at its rear and ware-discharging end. The chamber a is closed at its opposite end by suitably-applied doors a, as shown in Fig. 1. Que of the side walls of the casing A a short distance rearward from the doors a. is provided (see Figs. 2, 3, and 4) with a lateral doorway or inlet A, through which the ware which is to be annealed is fed into the chamber a.

Within the chamber a. between the inlet A and the doors a are two gasburners B, (see Figs. 1, 2. and 3,) arranged near opposite side walls, respectively, of the said chamber and connected in any approved manner and communicating with a gas-su 'iply pipe B, which is provided with a normally closed valve B The burners B are preferably so arranged relatively that the discharge-orifices b of each burner discharge opposite to and toward the discharge-orifices of the other burner, so that the flames issuing from each burner during the operation of the burners will project toward the flames issuing from the other burner, as shown in Figs. 1 and 3. Heat is therefore supplied during the operation of the burners B to the chamber a at the warereceiving or forward end portion of the said chamber between the inlet A and the forward extremity of the casing A.

The bottom of the chamber a is formed by an endless belt or conveyer which is arranged horizontally and extends longitudinally of the said chamber and, as shown in Figs. 2, 3, and 4., comprises two chains C and U, which are arranged a suitable distance apart widthwise of the chamber a and at the ware-discharging or rear end of the said chamber lead (see Fig. 3) over and operatively engage sprocketwheels U, which are operatively mounted on a shaft C, arranged horizontally below and transversely of the said chamber. The said conveyer extends past the inlet A, and the chains U at the are-receiving or forwardend portion of the chamber u. lead over sprocketwheels 0", arranged a suitable distance apart and mounted upon a shaft C, which is arranged horizontally below and transversely of the said chamber. (See Figs. 3 and a.) The shafts U and (1 are parallel and supported from the casing A, and the wheels of both pairs of sprocket-wheels (l and C are spaced apart correspondingly and arranged in line axially.

The chains (I carry metal plates (,f, which are arranged horizontally and extend transversely and form the bottom of the chamber a. The plates C are attached to linlrs of the chains C at the outer sides of the said chains. A portion of the chains (1 and attached plates is shown very clearly in Figs. 5, 6, and 7. The plates C are secured by suitably-applied bolts (1 and nuts C to flanges of arms 0, with which the links of the chains are provided.

Each plate C is wide enough to receive the article or ware to :be annealed, and, as will hereinafter appear, the conveyer comprising the chains C and attached plates C" is intermittently actuated, and the arrangement of the parts is such that the plates C of the said conveyer are successively brought into position to receive ware introduced into the forward end of the chamber a through the inlet A[ A driving-shaft D (see Figs. 1 and 2) is arranged horizontally a suitable distance above and transversely of the chamber a and a suitable distance rearwardly of the path of the ware into the said chamber, being supported from standards A resting upon and rigid with the casing A. The shaft D is provided centrally between its ends with a drivingwheel D, to which power is suitably applied. The shaft 1) is provided near its end which is farther from the inlet A (see Fig. 1) with a pinion D loosely mounted on the said shaft. The pinion D meshes with a gear E", operatively mounted on a shaft E, which is parallel with and arranged centrally between the shaft D, and a crank-shaft F, arranged rearwardly of the shaft D. The shafts E and F are arranged, therefore, horizontally and transversely of the chamber a and located above the casing A, being supported, respectively, from standards A and A, which rest upon and are rigid with the casing A. The intermediate shaft FJ is operatively provided with a pinion E, which meshes with a gear F, 0p eratively mounted on the shaft F. It will be observed, therefore, that power is transmitted to the shaft F from the shaft D upon establishing operative connection between the pinion D' and the said shaft D.

A clutch for controlling operative connection between the pinion D and the shaft 1) is provided and comprises (see Figs. 8 and 9) a member I), slidably and operatively mounted on the shaft 1.). and a relatively stationary member 1), formed on the pinion l). The operative connection between the shaft D and the slidable clutch member 1) comprises, preferably, the well-known means of groove and feather, as at D. It will observed that the said clutch is arranged between the pinion 1) and the driving-wheel I), and a collar I), mounted on and fixed to the shaft 1), is arranged as required to preventdisplacement of the said pinion endwise of the shaft farther from the slidable clutch member I). The clutch member I) is provided with an annular groove D, which is engaged by the roller R, with which a lever R is provided, which lever is applied and operated as will hereinafter appear.

. The crank-shaft F projects a suitable dis tance beyond the ware-receiving side of the chamber a and is provided at the said side of the said chamber with a crank which is operatively connected with a rod Gr, which is arranged externally of the said chamber at the said side of the said chamber between and engages the sheaves of any suitable number of corresponding pairs of guide-sheaves A", which are supported from the casing A, as shown in Figs. 2. and 11, and guide the said rod. The rod G is shiftable endwise and extends toward and adjacent to the ware-discharging or rear end of the chamber a, and the operative connection provided between the said rod and the crank of the shaft F (see Figs. 1 and 2) comprises, preferably, a pitman 1, which is attached to the said rod a suitable distance rearward of the said shaft, and the connection between the said pitman and the rod G consists, preferably, of a collar G, mounted on and adjustable endwise of the said rod and secured in the desired adjustment by a set-screw G. The pitman g is pivoted, as at g, to the collar Gr horizontally and transversely of the rod G. The pitman 9 extends from the collar Gr upwardly in the direction of the ware-receiving end of the chamber a and at its upper end terminates in an eye g which loosely embraces the wrist vf ofthe crank of the shaft F.

The said crank comprises a disk F which is operatively mounted on the shaft F, and the wrist f as shown very clearly in Fig. 10, is formed upon and projects laterally outwardly froma slide f, which engages and is adjustable endwise of a slideway-forming groove F, which extends transversely and radially of the disk F between and terminates a short distance from diametrically opposite points on the periphery of the said disk. Hence the groove F has end walls F*, and a screw f extends centrally and longitudinally of and through the said groove, and consequently through the slidef, andengages with corresponding screwthreads formed upon the surrounding wall of the screw-engaging bore f of the said slide, which therefore constitutes a nut. The screw f is stationary, so far as concerns endwise shifting of the screw when it is turned, extendingloosely through the end walls F of the groove F and having a head f, arranged at the outer side of one of the said walls, and a correspondingly threaded nut f engages the said screw at the outer side of the other of the said walls. It will be observed, therefore, that the stroke of the pitman r can he shortened or lengthened by a proper readjustment of the slidef and collar G".

A pawl G" (see Figs. 3 and 11) is pivoted at (a? to the rear end of the rod Gr horizonl l l i hangs and operatively engages a ratchet-wheel (5 which is operatively mounted on the shaft It is obvious that the ware-feeding conveyer of the annealing-chamber is upon establishing operative connection between the pinion D and the shaft 1) actuated in the direction required to convey any ware upon the conveyer toward the discharging or rear end of the said chamber and that the article or pieces of ware to be annealed are introduced through the inlet A into the said chamber to and upon the said co'nveyer. Each plate (J of the said conveyer has the dimensions required to accommodate a row of the said articles or pieces lengthwise of the plate and one article or piece widthwise of the plate. The said conveyer. is actuated intermittently, being moved every time a plate has been laden with a row of articles or pieces of ware far enough to remove the last-laden plate of the said conveyer from opposite the inlet A toward the rear end of the chamber a and to bring the next succeeding and unladen plate 0" of the said conveyer opposite the said inlet and in position to receive ware fed into the said chamher through the said inlet. The arrangement of the parts is such therefore that a plate U" of the said conveyer is always in position to receive ware fed into the chamber a. at the inlet A.

The casing A is provided at the bottom and outer side of the inlet A (see Figs. 2, 3, at, 12, and 13) with a rack it, which forms also the bottom of the said inlet and is arranged flush on top with or slightly above the upper or ware-receiving surface of the ware-carrying conveyer of the annealing-chamber (t. The rack 7a is arranged and adapted to receive the ware to be annealed. one article or piece at a time, preparatory to the passage of the said piece or article through the inlet A into the chamber a and onto the said conveyer. The article or'piece of. were to be annealed is delivered to and upon the rack A in any approved manner next to a stop-forming upright wall 71., with which the said rack is provided adjacent to the rear side wall of the inlet A, whereupon the said piece or article is engaged upon its side opposite to the inlet A by the head H of a rod H, which (see Figs. 2, 3, and 4:) is arranged in linewith the said inlet and horizontally and parallel with the ware-receiving plates 0" of the ware-carrying conveyer of the chamber a and extends outwardly from the said head.

The rod H extends (see Fig. 4) through and is adjustable end wise of two boxes .I and .l, which afford bearing to the said rod and are rigid with and supported from a reciprocating frame arranged and adapted to travel transversely of the chamber It and in a line parallel with the ware-carrying plates (1 of the conveyor, which frame comprises, preftally and transverselyof the said rod and overcrably, three parallel bars K, K and K,

which extend longitudinally of the said frame and are arranged at suitable intervals verti cally above and parallel with the rod H. The said bars K, K and K are rigidly secured at their outer ends to a vertically-arranged bar or piece K. The outer box Jis formed on the lower end of the upright bar K. Theinner box [is formed by and upon the lower end of a depending arm K*, with which the inner end of the lower bar K" is provided. The said lower bar K is therefore shorter than the rod H and arranged near enough to the said rod to render it capable of passing, with the said rod, through the inlet A during the operation of the warefeeding head H. The rod H is adjustablelongitudinally,asalreadyindicated, and secured in the desired adjustment by a suitably-applied set-screw H which extends into engagement with the said rod through a correspondingly-threaded hole formed in the box J. Itwill be observed, therefore, that a loosening of the set-screw H renders the warefeeding head H adjustable from and toward the ware-receiving rack h and enables an ac curate adjustmentof the said head relative to the said rack preparatory to the operation of the ware-feeding frame comprising the said head, which frameis normally in its outer position, as shown in Fig. 4. The upper bar K and the central bar K of the said frame form slides which engage correspondinglyarranged slideways L and L respectively, formed in and extending through an upright wall L, with which the top of the casing A is provided. The wall Lprojects upwardly from and extends transversely of the casing A, and the bars K and K are long enough to extend a suitable distance along the engaging slideways in the outer and normal position of the ware-feeding frame, so that the said frame is adequately supported in its said position. The arrangement of the parts is suchthat the head H in the outer and normal position of the said frame is arranged directly opposite the inlet A and far enough from the said inlet to accommodate thepassage of an article or piece of ware to be annealed onto the rack 71 between the said head andthe said inlet. The said head H has a concave face to render it capable of partially embracing the article received upon the said head and to be removed by the said head from the rack 71. through the inlet A into the chamber a, and obviously the' said head and any article delivered in advance thereof to and upon the said rack move toward and through the said inlet during the inward actuation of the aforesaid ware-feeding frame.

The central bar K of the warefeeding frame is toothed upon its upper side to form a rack K which has a travel therefore within and endwise of the slideway L during the reciprocation of the said frame, and moves transversely of and over the annealing chamber.

Arranged at right angles to the shaft 1),

en ear between the pulley D and the inlet A. and be: tween the said shaft and the path of the rack K, (see Figs. 1, 14:, and 1.5,) is a pinion-shaft k. The shaft/tis arranged above and longitudinally of the chamber aand extends over the path of the said rack. A pinion Z1 is operatively mounted upon the shaft 71; and meshes with the rack K, as shown very clearly in Fig. 4. The pinion Z? is arranged, therefore, withinthe wall L, which is slotted or cut away. as at L, to accommodate the location and operation of the said pinion. It will be ob served, therefore, that the rack K, and consequently the ware-feeding frame, are shifted endwise in the one or the other direction, according as the pinion-shaft is rotated in the one direction or the other, and obviously the ware-feeding device H of the said frame is caused to remove any article upon the rack it through the inlet A into the annealingchamber a or is withdrawn from the said chamber according as the said frame is actuated in the one or the other direction.

Power is transmitted to the pinion-shaft 71: from the driving-shaft K, and the means employed in transmitting the said power comprises two corresponding oppositely-arranged bevel-gears (Z and 06 which (see Figs. 1 and 15) are loosely mounted on the said drivingshaft atopposite sides, respectively, of the pinion-shaft and mesh with a bevel-gear 7t, operatively mounted on the pinion-shaft between the gears d and d An endwise-shiftable sleeve d is operatively and slidably mounted upon the driving-shaft between the gears d and (Z The operative connection between the sleeve d and the driving-shaft comprises, preferably, the well-known means of groove and feather, as at (Z A clutch for controlling operative connection between the gear d and the shaft D is provided. One member (Z of this clutch is formed on the gear d, whereas the companion clutch member d is formed on the adjacent end of the sleeve (Z, and obviously the last-mentioned or movable clutch member (1 is actuated into or out of operative engagement with the relatively stationary clutch member (Z according as the sleeve If is shifted endwise far enough in the direction of the said gear or moved away from the gear. Another clutch for controlling operative connection between the gear (Z and the shaft D is provided, and the movable member (i of this clutch is formed on the sleeve (Z, whereas the relatively stationary member (1 of the said clutch is formed on the said gear, and obviously the movable clutch member (5 is actuated into or out of operative engagement with the relatively stationary clutch member d" according as the sleeve (Z is shifted end wise far enough in the direction of the gear (Z or moved away from the said gear.

In the normal position of the parts the sleeve 1/ is in its central position, as shown in Figs. ll and lb, centrally between the gears clutch-controlling operative connection be-v tween the said shaft and the gear (1. is ren dered operative according as the sleeve (2 is actuated endwise far enough in the one or th other direction.

The means employed in actuatin the sleeve 1! (see Figs. 1, 2, 14, 15, 16, and 17 comprises a lever e, which is arranged above and longitudinally of the chamber a and extends in under and transversely of the shaft D, being fulcrumcd vertically, as at e, to the top of.

the casing-A between the shaftD and 'the shaftE. The lever 6 has a roller-bearing arm 6', whose roller engages an annular groove (1, with which thesleeve d is externally provided. The lever e is provided with an arm a, which projects from the fulcrum e rearwardly. A lever m extends transversely of the upper side of the arm 6* and is fulcrumed horizontally at one end, as at m, tothe top of the casing A at one sideof the said arm, and at the opposite side of the said arm is provided with a poise m. The lever m is provided'at its under side with an inclined shoulder m, which slopes upwardly in the direction in which the lever-arm e moves during the actuation of the lever e in the'direction required to shift the movable clutch member 03 into operative engagement with the companion clutch member (.5 in rendering the gear d operative. In the normal position of the parts, as already indicated, the lever e is in an intermediate position holding the sleeve OZ in its intermediate position, wherein the clutch members carried by the said sleeve are out of operative engagement with the relatively stationary clutch members formed on the gears d and (Z and the lever-arm a is in position at the lower. end of the incline m, as shown very clearly in Figs. 14 and 16.

A slide 17. is arranged externally of the annealingchamber and .longitudinally of the ware-receiving side of the said chamber. The slide a (see Figs. 2, 3, 12, and 13) engages a correspondingly-arranged slideway A with which the casing A is externally provided at and adjacent the bottom of the inlet A between the said inlet and the rear end of the annealing-chamber. The slide at is provided, at its rear end and beyond the rear end of the slideway A, with a standard 72., which is provided with a rearwardly-projecting arm n (See Figs. 2, 3, and 14.) The casing Ais provided, between the standard n and the inlet A, with an arm or bracket A which overlaps the outer side of the said standard and is provided with a guide-sheave A". A cable N, by means of which a poise or weight N is suspended, leads over the forward side and top of the sheave A to the rear end of the-arm n, to which the said cable is attached in any approved manner. The poise N acts to retain the slide in its forward andnormal position, whereina stop -such, for instance, as the rear side of the bracket A is engaged by the forforw'ard movement of the slide beyond its for-. ward and normal position. The lever e (see Figs. 2, 14, 15, and 17) has an arm a which projects in the direction of thepath of the re-' ciprocatory ware-feedingfframe-and is nor mally engaged at its freeiendand at its. side edge which faces 'tlieT Iyvare-receivingside of the annealing-chamber by'the'inner end of a latch I, which is pivoted vertically centrally between its ends, asfat-lfytothe top of. thecasing A, and consequentlycapableof being swung in a horizontal plane. The latch lex- 'tends from the lever-arm e inthedirection ofthe path of the slide n, and asuitably-a'pplied spiral spring 7 acts to retain the said latch in its normal position. The spring Z isshown 'ward side edge of the standard'n' and prevents attached at one end to the outer arm of the latch and at its opposite end to the upwardlypro ecting. wall L of the casing A. A vertieally-tiltable dog 0 is pivoted horizontally, as.

at 0, to the outer end and longitudinally'of the outer arm of the latch Z and projects or depends from the latch in the direction of the aforesaid ware-feeding frame. The dog 0 is free to swing upwardly, but rests below its axis upon the free end of the outer armof the latch Z, so that the latter is prevented from tilting downwardly. The standard n'is provided at its upper end with an arm wa which projects forwardly in the direction of the. path of the ware-feeding frame, and is provided at itsfree end with an upwardly-projecting member 92, arranged to bear rearwardly against the-forward side of the lower end of the dog 0.

A plate 11, which is preferably, but not necessarily, yieldable vertically, is (see Figs. 14, 15, and 17) supported from the arm 11 and preferably pivoted, as at p, horizontally and transversely at the free end of and to the said arm. The plate p extends from the free end of the arm n rearward ly and has an upwardly and rearwardly sloping upper side. A spiral spring 19 is interposed between the under side of the plate p and a laterally and outwardly projecting flange 11F, with which the armn is prdvided, and acts to retain the said plate in its upper and normal position. The plate p is the'reforecapable of being depressed against the action of the said spring 2 and is consequently ,vieldable vertically. The plate 10 is reduced in width toward its rear and free end, so that outer side edge of the said plate forms an incline 19 which extends from'the rear and free end of the plate outwardly and forwardly.

A bar Q, arranged horizontally and transversely of the top of the casing A, (see Figs. 14, 15, and 17,) is pivoted vertically, as at Q, to the arm 0 of the lever 12 and extends later- ITS of the bar Q, provided with two depending arms Q and Q arranged a suitable distance [apartlongitudinally of the said bar.

(See Fig. 17.) A slideWay-formingrod Q which is arranged below and longitudinally of the bar Q, extends between the lower ends of and is supported from the arms Q. are provided also with a rod Q, which is arranged parallel with the rod Q and extends loosely through and steadies the slide-forming collar M, which is slidably mounted on the rod Q a suitable distance from the outer arm Q and preferably next to the outer side of the inner arm Q and a spiral spring Qfis mounted and confined upon'the rod Q between the outer end of the said collar orslide M and the outer arm Q and acts to retain the said slide in its inner and normal position. The slide M is provided with a depending member, which is preferably in the form of avertically-arranged antifriction-rollerM', which in the normal position of the parts engages the inner and rear end of the incline f. It will be observed, therefore, that during the actuation of the slide a rearwardly the memher it of the said slide through the medium of the dog 0 renders the latch Z inoperative by swinging the latter in the direction required to release the lever-arm e, that while the latch is being rendered inoperative the roller M, and consequently the slide M, are, by means of the incline-p actuated. laterally and outwardly in the direction required to compress the spring Q, and the arrangement of the parts is such that the said spring shall not be fully compressed until the latch I has been rendered inoperative, whereupon a further actuation of the slide at in the same dian outwardly endwise shifting of the bar Q, and thereby operate the lever e, as required, to shift the sleeve 62 in the direction of the path of the said slide and establishoperative engagement between the members of the clutch-controlling operative engagement between the driving-shaft D and the gear (1', and the spring Q, having been compressed, operates to insure an adequate operative engagement of the clutch member d with the clutch member d until the clutch member d is again actuated out of engagement with the clutch member d. During the said actuation of the said lever the arm a of the lever moves in under and along the shoulder of, so as to enable the poise m to facilitate the said actuation of the said lever and to retain the lever in position holding the clutch member of in the proper engagement with the clutch member d i The driving-shaft D is rotated in the direc- The arms Q tion indicated by the arrow 2 1 in Figs. 14 and 15. The reciprocatory ware-feeding frame is normally arranged in its outer position, as alreadyindicated, ready to remove an article or piece of ware delivered to and upon the rack 71. through the inlet A onto the ware-feeding conveyer of the annealing-chainher,and the arrangement of the parts is such that the establishment of operative connection between the gear (1 and the shaft D will, through the medium of the bevel-gear Z pinion-shaft 7t,

pinion F, and a rack K result in the inward actuation of the said frame.

It willbe observed that operative connection between the gear d and the driving-shaft D is effected preparatory to each inward or ware-feeding movement of the ware-feeding frame and that the said opertive connection must be interruptedand in lieu thereof operative connection established between the gear al and the said shaft preparatory to each return or reverse movement of the said frame; that the said frame in order to arrange the ware, which is fed by its ware-engaging device H into the annealing-chamber in rows upon and transversely of the ware-feeding *conveyer'of the said chamber must in feeding the first member of a row of ware be actuated the maximum distance, so as to move the said member of the row to be formed farther from the inlet A than the remaining and subsequently fed members of the said row and that the travel of the said frame during each subsequent ware-feeding movement thereof in the formation of the said row must be enough shorter than the next preceding ware-feeding movement of the said frame to free the article or piece of ware next previously fed by the said frame, and consequently the shortest travel of the said frame will occur when the last member of the said row of ware is being fed into the annealing-chamber. It is obvious, therefore, that the pinion-shaft k must be rotated longest without interruption during the ICC when the first memberof each row of ware interval of time enough shorter than the time taken in having fed the next previously fed article or piece of ware to avoid collisionwith the last-mentioned piece or article on the said conveyer.

At the top and rear side of the travel of the ware-feeding and rack-bearing frame is a shaft T, which is arranged horizontally and transversely of the casing Aand parallel with the said travel. The shaft 1 extends from end to end of the said frame. The shaft T (see Figs. 1, 2, 4:, 1 1, 15, and 18) has bearing in two boxes K and K, with which the bar -on the said conveyer must be rotated for an feeding of ware to the annealing-chamber &

scopes '7 K of the said rack-bearingframe is provided, which boxes are arranged a suitable distance apart longitudinally of the said frame. The boxes K and K are formed on brackets K, which project laterally of the rack-bearing frame and rearwardly, and the wall L,--at the rear of the slideway L, is slotted or recessed,

as at L, (see Figs. 15 and 18,) to accommodate the location of the brackets K and avoid obstruction by the said brackets to the operation of thesaid frame.

The shaft T is provided at the inner end of the outer box K with a collar secured to the said shaft in any approved manner. The shaft T is provided at its inner end with a collar T fixed to or formed on the shaft in any approved manner. It will be observed, therefore, that the shaft T is not only supported from-the ware feeding frame, but is prevented from endwise displacement independently of the said frame without interfering with the rotation of the shaft.

The shaft T is provided with as many laterally-projecting members 25' as there are articles to be placed in a row within the anneallug-chamber va, which members are spaced equidistantly longitudinally of the shaft as well as at equal intervals circumferentially of the shaft. In the machine illustrated the shaft is provided with twelve projecting members If, and each member 6 projects from and is rigid with a collar T mounted on the shaft T and secured in the desired adjustment by a suitably-applied set-screw T, which is preferably countersunk in the said collar. The outermost member 6 is formed by an.annular flange with which the outermost collar T is externally provided, and each remaining collar T is formed by a pin inserted in and fixed to the said collar in any approved manner. The outermost collar T is one of the collars which participate in preventing endwise displacement of the shaft T.

The collar T is shown fixed to the shaft T by a suitably-applied set-screw z". The collar T (and consequently the shaft T, of which the said collar forms a member) is provided with as many radially-arranged and laterally-projecting pins 6 as there are projecting members 2 on the said shaft. The shaft T shown is provided, therefore, with twelve members 6 spaced equally circumferentially ofethe collar T and one of the said members i is longer and projects farther from the shaft than the remaining members t as at 25.

' A dog it is pivotally supported from the upper portion of the wall L of the casing A over the pinion k being pivoted to the said wall, as at u, horizontally and longitudinally of the casing A, and therefore arranged to swing in a vertical plane. in the direction in which the ware-feeding and shaft-bearing frame is actuated in feeding ware into the chamber (L. The dog 11 over- The dog a projects said wall and extends rearwardly beyond the rear side of the said wall. The dog-u is provided at its rear side with an incline 1.1 which slopes rearwardly and toward theware-receiving side of the chamber a and is arranged to be engaged by a member t of the shaft 1 during each outward or return movement of 1 tli e vare-feed-ing frame. The under side of the dog It slopes, as at a, downwardlytoward the free extremity of the dog, and the sloping surface a is arranged in the path of a member. t of the shaft T during the inward or feeding movement'of the ware-feeding frame. The lever e is provided with another arm 6 which projects into close proximity to the shaft T betweenthe innermost member t of the shaft T and an annular shoulder t, formed on the said shaft by the inner end of the collarT The lever e is arranged to be engaged by one of the projecting members -t of the shaft T'during each inward or feeding movement of the rack-bearing ware-feeding frame and is'engaged by the shoulder i of the shaft T during .each outward or return movement of the said frame. go The slide it is operated by pushing rearindicated, in its intermediate position; that upon rendering the latch Z inoperative, as hereinbefore described, the lever e is actuated toward the ware-receiving side of the chamher a and operative connection is established between the gear d and the driving-shaft D, and consequently between the rack K and the said shaft, so that thewarefeeding frame and its shaft T begin to move inwardly; that during the first inward stroke. of the saidframe the outermost projecting member t of the shaft T shall comev into engagement'with the arm '6 of the lever e and thereupon actuate the said lever to interrupt operative con- I ne ction' between the rack K and the drivingshaft D and arrest the inward movement of the said frame when the. -article which is to be fed by theware-feding device of the said frame during the said movement of the said frame has passed into the annealing-chamber and into place upon the conveyer of the said chamber; that a member 6 of the shaft T shall pass in under and into engagement with the sloping lower surfacem of the upwardlyswingable dog a during the said inward movement of the shaft T and result in idly swinging the said dog upwardly; that during thenext succeeding outward or return stroke of result in turning the shaft one-twelfth of a rotation and in the direction required to bring hangs the wall L and normally rests upon the i the second outermost projecting member t of the shaft T into position to actuate the lever preparatory-to and during the next inward stroke of the ware-feeding frame, and that the remaining .members 15 of the shaft Tshall be operated in turn by the incline n of the dog u, so as to oscillate the said shaft onetwelfth of a rotation during each outward or return stroke of the said frame, and thereby bring each projecting member 6 of the shaft T in position in turn to actuatethe aforesaid lever e. The collar T, being secured to the shaft T by a set-screw, is consequently removable from the shaft upon loosening the said screw to accommodate. the placing upon the said shaft of a collar havinga less or greater number of radially-projecting members i as would be required in forming rows of ware upon the conveyer of a smaller or greater number than twelve. Obviously the projecting shaft members 25 are rendered free to be adjusted longitudinally of the shaft T upon loosening the set-screws T of the col.

lars T, which when loosened can be removed from the shaft upon the removal of the collar T to accommodate the arrangement upon the shaft of a smaller or larger number of collars,

.part is such that the lever-arm 0 upon the actuation of the lever by the shoulder t is disengaged by the said shoulder when the said lever has been actuated into its intermediate position, as shown in Fig. 1 1.

The twelfth operating member 25 which participates in the operation of the ware-feed ing frame in returning the said frame to its outer and normal position next after feeding the last article of a row of articles onto the conveyor of the annealing-chamber, is somewhat longerthat is, projects farther from the shaft T, as at 25--than the remaining projecting member 25 of the said shaft and has its outer end arranged to come into engagement during the said return movement of the said frame and before turning 'the said shaft during the said return movement of the said frame with a horizontally-swinging dog 0 which is pivoted vertically, at 20', (see Figs. 1, 8, 9, and 15,) toa bar an, arranged above the casing A and resting upon a standard A,

with which the top of the said casing is provided. The barrcis arranged horizontally and transversely of said casing, and consequently longitudinally of the travel of the rack K of the ware-feeding frame. The dog to normally projects in the direction of the said travel.

The slidable member of the clutch controlling operative connection between the pinion an annular groove D which, as already indi- 'D and the driving-shaft D is provided with cated, is shown in Figs. 1, 8, and 9 and is en- A suitably-applied torsional spring R" is attached to the post or standard A. and acts to retain the lever R in position, holdmgthe engaging clutch member D in operative engagernent with the companion and relatively stationary clutch member D which spring, as shown in Figs. 1 and 8, has one end thereof overlapping the said lever near the fulerum of the lever between the lever and the ware-receiving side of the annealing-chamber (6.

. The lever It extends to and over the intermediate shaft E and supports an endwiseshiftable rod 7, which is'arranged over and longitudinally of the lever Band has bearing in two boxes R and R, with which the said lever is provided. The rod 9' extends through the outer or rear box R* and at its rear end is provided with a head 1", adapted to be engaged by a cam 26, with which the gear F of the crank-shaft F is provided.

A sleeve 1 is slidably mounted on the rod 1' centrally between the boxes R and R and a spiral spring r is mounted and confined on the said rod between the said sleeveand the inner box R The sleeve y is operatively connected by means of a link 3 with the short arm of a bell-crank g which is fulcrumed vertically to the upper endof the standard or post A, and preferably the axes of the levers R and'y are coincident. The short arm of the bell-crank f projects in the direction of the pinion D and the long arm of the said bell-crank projects in the direction of the travel of the ware-feeding frame and isvertic ally pivoted at its outer end, as at to the adjacent end of the bar or, which is located between the driving-shaft and the travel of the ware-feeding frame and rests, as already indicated, upon the upper end of the standard A. The bar 00 extends from the bell-crank toward the outer end of the ware-feeding" frame and is held to the standard supporting it by a lug or pin 27 with which the said standard is provided and which projects upwardly from the standard into a diagonally-arranged slot a, formed in the saidbar. The spring o acts to retain the bell-crank y and consequently the connected bar as, in their normal position. The bar m carries the dog w, as already indicated, and an upwardly-projectinglug or member .0? with which the said bar m is provided is arnormal position, wherein the dog engages the aforesaid stop-forming member :r of the bar The spring Q02 is shown attached at one end to the rear end of a rearwardlyprojecting arm w with which the dog w is provided and at its opposite end to and centrally between the ends of the bar .1. Obviously the dog is free to swing in the direction in which the ware feeding frame moves during the ware-feeding movement of the said frame.

The arrangement'of the parts is such that normally the cam 26 holds the clutch member D, through the medium of the rod 1- and lever R, in its inoperative position against the action of the spring R; that the farther projecting member t of the shaft T duringthe lastfeeding operation of the ware-bearing frame in feeding the last member of a row of ware to and upon the conveyer of the annealing-chamber idly swings the dog In in passing by the said dog; that the said member 25 of the said shaft during the next outward or return movement of the said frame engages the opposite side of the said dog and thereupon actuates the bar m in the direction of the outer end of the travel of the said frame and results in the actuation of the bell-crank y in the direction required to pull upon the connected rod 0* in the direction of the said travel of the said frame, and consequently to shift the said rod endwise against the action of the spring 0- until the head a" of the said rod is disengaged from the cam 26 of the wheel F during the rotation of the said shaft subject to the action of the spring R which thereupon actuates the lever B in the direction of the pinion D and results in establishing 0perative connection between the said pinion and the shaft 1), and consequently in the actuation of the aforesaid conveyer the distance required to bring the next succeeding plate 0" of the said conveyer into position to receive ware fed into the annealing-chamber at the inlet of the said chamber.

As already indicated, the slot 1: in the bar as is diagonally arranged, and consequently extends longitudinally as well as transversely of the bar, and the pinor projecting member 27 of the standard A normally engages the rear end of the said slot. dog w is actuated in the direction of the warereceiving side of the annealing-chamber by the outer end 25 of the longer pin or projecting member t of theshaft T the bar in is actuated not only toward the ware-receiving side of the said chamber, but toward the rear end of the said chamber, and the arrangement of the parts and the-length of the slot m are such that the aforesaid member 6 of the shaft '1 during the operation of the bar w by the Hencewhen the said member 25 shall release the dog to as soon as the head '1" of the rod ris released from the cam 26, and the arrangement'of the parts is such, furthermore, that the cam 1", having I been disengaged by the head 1" of the rod r, again engages the said head and has again rendered the clutch member D inoperative upon the required actuation of the conveyer ofjthe annealing-chamber. I .As already indicated, the longer of the shaft members t is actuate'd'tooperate the bar a;

and connected mechanism during the last outward or return movement of :the ware-feed ing frame in forming a row of articles or ware upon the conveyer of the annealingchamber and before the shaft '1 is turned during the said movement of the said frame, and Fig. 15 shows the shaft turned during the said movement of the said frame, and consequently shows the last operating and longer member of the series of shaft members t moved outof operative position relative to the dog to. 7
